METALLIC FASTENER OR JAMB NAIL.

Application filed May 22,

This invention relates to metallic j amb nails or fasteners, such as are adapted to be used for securing and holding door j ambs or window jambs, or the like, in place; and has for its object the production of an improved metallic fastener or jamb nail which is simple and economical of construction, efficient in operation, and adapted to be secured in position with facility and accuracy, and to securely hold the j amb of a door or window, or other article in connection with which it is to be used, in place.

A further object of the invention is to provide an improved jamb nail or fastener having pointed prongs which are adapted to be driven into the material to which the fastener is to be secured, and bent or clinched, or spread at the sharpened ends, bythe operation of driving in the prongs either into wood, or into plaster or fiber board or other similar material which may be softer than wood and not sufliciently firm to bend or cause the spreading apart or clinching of the pointed prongs to the desired extent merely by the resistance ofiered to the prongs by the material into which they are to be driven.

Other and further objects of the invention will appear from the following description, and from the accompanying drawings, which are made a part hereof.

The invention consists in a metallic fastener or jamb nail, adapted to be used for securing and holding door jambs, or window jambs. or the like, in place and in the construction and arrangement of parts, and combinations of elements herein described and claimed.

In the accompanying drawings Figure 1 is a view inelevation of a door j amb or window jamb provided with metallic fasteners or jamb nails for securing and holding the j amb in place,'with parts of the jamb broken away or omitted. for the purpose of clearness of illustration.

Fig. 2 is an enlarged detail View in section. taken on line 22 of Fig. 1, looking in the direction indicated by the arrows, and showing the jamb provided with metallic fasteners or jamb nails constructed in accordance with my invention.

'The- :transverse recess thus-. formed at thcbaseot eachprong andtencthea. liner side of the angle attheapex of whichthe bases of the prongs are unitedwith ithez main body portion, is adaptedto receive material which may be displaced by= cthe prongs when they are driveninto; wood,r; plast r, fiber board on other material. 'llltfifx'; which the prongs are adapted. to be driven by striking upon the protuberance,ornproj ction formed by theprotruding transverse .rib or head 1.2. with a hammer or-other Stilt-3(- able instrument or tool.

A central r cessor opening l i;is,-=by-1t reterence. provided inthermaterial which is bentto for: rthe.angulaiwpronged end of thefastener. This opening may berelongated lto' any desired extent so=as1to :torn'i a centr l :slotoi: groove which maybe open atone e tremity and thus provide anrndopening .or space between theignongs lO,=10;-at;their 1 bases as well as between their inner-tapered or inclined side inarg-insall, l1',:'and1between' Y the sideportions or strips 15, located on opposite sides of the recess or slot 14: and; :wi; which the bases-oftheprongsand the .hollewtransverse .protrndingsrib 121are all; econnected integrally (See 3, 15, 6 and '7.) The recess orslot- :14 may thus; tend between andseparate -=th.e-boin prongslf) and provide a spz'icebe'tween the r1 bases of. the prongs-and.between-{the thus. .ssparated parts of the transverse, rib: or prov! tulmrance 12; which is adapted towreceive; or permit the extrusionoit material displaced. q by the prongs as they are driven intonadoonn jamb, windm jarnb. plaster,'fibenboard or other materiat to which the. fastener-is to. be secnred. or structurein connection-with? which the device is to be emplovech The protuberances-or projecting shouldersward, so as to cause the sharp points of the prongs to be spread apart by the force of the blows thus applied, and that the spreading of the prongs will be effected, not merely by the resistance afforded by the material into which the prongs are driven coming into contact with the inner inclined margins of the prongs 10, but by the force of the blows of the hammer applied to the projecting shoulders or protuberances or heads 12, which, being'applied, by preference, with greater force to the inner margins 23 of the projecting parts 12 tends to twist the side strips 15, 15 on opposite sides of the opening let and to spread the sharp pointed ends of the prongs 1O apart or in opposite directions, in the material. And it should be noted that this mechanical spreading of the pointed ends of the prongs is thus effected regardless of whether the material into which the prongs are to be driven is sufficiently strong or hard to cause the bending or spreading of the prongs or not. prongs may thus be driven into relatively soft material, such as plaster, or fiber board, and spread or forced apart in such material or in any desired suitable material, so that the fasteners may be firmly secured and strongly held in place without dependingupon the material into which the prongs are driven to spread them apart or to bend the prongs. The prongs 10 may thus be driven into any suitable material and spread apart as shown in Fig. 6,-for example, into a door jamb or window jamb, or into plaster, or plaster and lath, or other structure, as desired.

The fasteners or jamb nails 8 are more particularly intended and adapted to be used for securing door jambs and window-janibs in place, and for positioning and securing the jambs or inner frames of doors or windows, or the like, to the studding. (See Figs. 1 and 2.) The main body of each fastener 8 is therefore, by preference, provided with a series of perforations 16 adapted to receive nails 17, which may be driven through saidopenings into studding or other structures to which the fasteners are to be secured. And the central opening or elongated slot 14 is, by preference, adapted to receive a headed nail 17 which may be driven therethrough into a door jamb or window jamb or other structure. The head of a nail may thus be driven into contact with the inner margins of the protruding shoulders The 01' heads 12, 12, if desired, so as to force said inner margins down or inwardtoward and into contact with the face of the janib or material into which the prongs are driven, thus tending to spread the pointed ends of the prongs apart. The spreading of the prongs may thus be accomplished either with or without the use of a nail.

A nail not being required for this purpose,

it is ordinarily only used when found desirable for furnishing an additional fastening means to supplement the prongs, which are ordinarily sufficient without the use of a nail in slot 14.

Each fastener 8 is, by preference, provided with an indicator mark or device 18 for indicating the proper position of the margin of a door jamb or window jamb or other structure with respect to the prongs to be driven into such structure. The indicator mark or device may be in the form of V a transverse raised rib or shoulder extending across the body of the fastener, or may be an indentation or graduation, or mark of any desired or suitable form, no raised rib being required. A pro ecting stop or positioning boss 19 may be provided, which may be formed by bending themetal strip displaced in making the central slot or opening ltthus forming an integral stop on the inner side of the main body portion of the fastener which j amb, or other structure into which the pointed prongs 10 are to be driven, when the device is in operation. The stop 19 may, however, be made by cutting and bending the strip of metal of which it is formed fromany desired part of the sheet metal body of the fastenei or said stop may be dispensed with if desired.

The central opening or slot 14 may extend between andfseparate the normally projecting bases of the prongs 10, as well as between the integral side marginal strips 15, 15 which are integral with the bases of the prongs 10 and connect the same with the main body portion 9, which is, by preference flat, as shown in Figs. 3 to 8 inclusive; or said slot 14imay befclosed at both ends, and a mere closed slit 14' may be provided between the inner adjacent opspreader elements or wedging shoulders 20 to :spread or tend-t0 spread and hold-1. orv p Cll1V-8I1; and eitherthe? outer. fastener; of.
